A fluorine-containing material substrate having coated thereon a pressure sensitive adhesive is irradiated with an electron beam, forming a chemical bond between substrate and the pressure sensitive adhesive. Furthermore the pressure sensitive adhesive can be cured by polymerization and also the substrate can be crosslinked.

Pressure sensitive adhesive sheet and production method thereof

This invention provides a method of bonding substantially non-fluorinated polymeric material to a fluoropolymer utilizing a bonding composition comprising primary or secondary di- or poly-amine and a melt-processable, substantantially non-fluorinated component. Multi-layer articles and composite constructions, including retroreflective sheeting and fuel line hoses, made of a fluoropolymer layer and a substantially non-fluorinated layer are also provided.

Multi-layer compositions comprising a fluoropolymer

A multi-layer article comprising a substrate and a dehydrofluorinated fluoropolymer, wherein the dehydrofluorinated polymer contains substantially no grafted adhesion-promoting groups, and the dehydrofluorinated fluoropolymer contains sufficient carbon-carbon unsaturation to increase the adhesion between the dehydrofluorinated fluoropolymer and the substrate.

Method of improving adhesion between a fluoropolymer and a substrate

A multi-layer article comprises a substantially non-fluorinated layer, and a fluorinated layer of fluoropolymer comprising interpolymerized monomeric units derived from one or more of hexafluoropropylene and tetrafluoroethylene monomers, one or more non-fluorinated olefinically unsaturated monomer, and substantially no vinylidene fluoride monomer. The multi-layer article further comprises an aliphatic di-, or polyamine which provides increased adhesion between the layers as compared to a multi-layer article not containing the aliphatic di-, or polyamine. The multi-layer article can be prepared by mixing the aliphatic di-, or polyamine into the substantially non-fluorinated polymeric material, or by applying the aliphatic di-, or polyamine to a surface of one or more of the substantially non-fluorinated polymeric material or the fluoropolymer, and thereafter preparing a multi-layer article.
